[0040] Please refer to Figures 1 to 8 The present application provides a spliced steel structure 10, which comprises a connecting piece 100, a plurality of cross beams 200 and fasteners 300. The connecting piece 100 is provided with a plurality of fixing grooves 110 and threaded holes 120 communicating with the fixing grooves 110. The cross-sectional area of the plurality of cross beams 200 is adapted to the cross-sectional area of the fixing grooves 110, and each cross beam 200 can extend into any fixing groove 110. The extension direction of the plurality of cross beams 200 is provided with a positioning groove 210. The plurality of fasteners 300 are respectively threadedly connected with any threaded hole 120 and abut against the groove bottom of the positioning groove 210.

[0041] Specifically, the spliced steel structure 10 comprises a connecting piece 100, a plurality of cross beams 200 and a plurality of fasteners 300. The connecting piece 100 is provided with a plurality of fixing grooves 110 and threaded holes 120 communicating with the fixing grooves 110. The cross-sectional area of the plurality of cross beams 200 is adapted to the cross-sectional area of the fixing grooves 110, and each cross beam 200 can extend into any fixing groove 110 and is provided with a positioning groove 210 in the extension direction. The fastener 300 is threadedly connected with the threaded hole 120 and abuts against the groove bottom of the positioning groove 210, thereby achieving stable fixation of the cross beam 200. During installation, the cross beam 200 is initially positioned by being inserted into the fixing groove 110, and then the fastener 300 locks the cross beam 200 through the threaded hole 120, so that the cross beam 200 is tightly combined with the connecting piece 100. This structure avoids the complicated installation and alignment error caused by the traditional butt joint mode of the cross beam 200, improves the splicing precision, and reduces the possibility of deformation of the cross beam 200 under stress.

[0042] The installation convenience, connection stability and structural adaptability are remarkably improved. Firstly, the standardized connecting piece 100 and the fixing groove 110 design enable the cross beam 200 to be quickly inserted and positioned, reducing the construction adjustment time and improving the splicing efficiency. The connecting piece 100 has a plurality of fixing grooves 110 to connect a plurality of cross beams 200, making the splicing mode more flexible and being able to meet various building requirements.

[0043] Please refer to Figures 2 to 5 In an embodiment, two clamping structures 140 are arranged in each fixing groove 110, and the two clamping structures 140 are symmetrically arranged. Each cross beam 200 is provided with two clamping grooves 220, and the size and shape of the two clamping structures 140 are respectively matched with one clamping groove 220. The two clamping structures 140 are respectively clamped in one clamping groove 220.

[0044] Specifically, two clamping structures 140 are arranged in each fixing groove 110, and the two clamping structures 140 are symmetrically arranged. The cross beam 200 is provided with two clamping grooves 220, and the size and shape of the two clamping structures 140 are respectively matched with one clamping groove 220, so that the clamping structure 140 can be stably embedded in the clamping groove 220. Through this design, when the cross beam 200 is inserted into the fixing groove 110, the clamping structure 140 and the clamping groove 220 can provide support and limiting action, enhancing the stability of the cross beam 200 at the connection. At the same time, due to the cooperation of the clamping structure 140 and the clamping groove 220, the cross beam 200 can be automatically aligned during installation, avoiding the problem of inaccurate installation caused by error accumulation in the traditional splicing mode, and improving the construction precision and splicing quality.

[0045] Please refer to Figure 3 and Figure 4 In an embodiment, each clamping structure 140 includes a connecting part 141 and a clamping part 142, the connecting part 141 is fixedly connected with the inner wall of the fixing groove 110, and the connecting part 141 is fixedly connected with the clamping part 142.

[0046] Specifically, the connecting part 141 is fixedly connected with the inner wall of the fixing groove 110, ensuring that the clamping structure 140 is firmly attached in the fixing groove 110, and the clamping part 142 is fixedly connected with the connecting part 141, for realizing the stable clamping of the cross beam 200 and the connecting piece 100. Through this structure design, the clamping part 142 can closely fit the clamping groove 220 of the connecting piece 100 during connection, so that the cross beam 200 can not only be locked by the fastener 300 when inserted into the fixing groove 110, but also can provide additional mechanical support through the clamping structure 140, improving the connection stability of the cross beam 200.

[0047] Please refer to Figure 3 and Figure 4In an embodiment, the clamping structure 140 comprises a plurality of protrusions 143 fixedly connected with the clamping portion 142, and each of the cross beams 200 is provided with a plurality of recesses 230 in communication with the clamping grooves 220, and the protrusions 143 are sized and shaped to fit the recesses 230, so that each of the protrusions 143 is clamped in one of the recesses 230 when each of the clamping structures 140 is clamped in one of the clamping grooves 220.

[0048] Specifically, the clamping structure 140 comprises a plurality of protrusions 143, and each of the cross beams 200 is provided with a plurality of recesses 230, so that each of the protrusions 143 is clamped in one of the recesses 230 when each of the clamping structures 140 is clamped in one of the clamping grooves 220. The recesses 230 on the cross beams 200 are in communication with the clamping grooves 220, so that the protrusions 143 can be accurately clamped in the recesses 230 after the clamping structures 140 are inserted into the clamping grooves 220, thereby achieving multi-point clamping and fixing.

[0049] Please refer to Figure 2 In an embodiment, the positioning groove 210 is in communication with the clamping groove 220, and the plurality of fasteners 300 comprises a nut 310 and a stud 320 fixedly connected with the nut 310, and the width of the positioning groove 210 is equal to the diameter of each of the studs 320. The connecting piece 100 is provided with a plurality of cap grooves 130, each of which is in communication with one of the threaded holes 120. The stud 320 passes through the cap groove 130 and the threaded hole 120 in sequence and is threadedly connected with the threaded hole 120, and the bottom of the stud 320 abuts against the groove bottom of the positioning groove 210, and the nut 310 is arranged in the cap groove 130.

[0050] Specifically, the positioning groove 210 is in communication with the clamping groove 220, so that the cross beams 200 can form a more compact fit after being inserted into the connecting piece 100. The plurality of fasteners 300 each comprises a nut 310 and a stud 320, and the diameter of the stud 320 is equal to the width of the positioning groove 210, so that the stud 320 can be accurately clamped in the positioning groove 210, thereby preventing the cross beams 200 from being deviated during splicing. The connecting piece 100 is provided with a cap groove 130 in communication with the threaded hole 120, and the stud 320 passes through the cap groove 130 and the threaded hole 120 in sequence and is threadedly connected with the threaded hole 120, and the bottom of the stud 320 abuts against the groove bottom of the positioning groove 210, and the nut 310 is arranged in the cap groove 130. The design of this structure ensures that the fastener 300 provides a fastening effect, thereby preventing the cross beams 200 from being loosened or misaligned due to external force or vibration.

[0051] Please refer to Figure 2 and Figure 5 In an embodiment, the connecting piece 100 is provided with threaded holes 120 on both sides, and the threaded holes 120 pass through the protrusions 143 and the clamping portions 142.

[0052] Specifically, both sides of the connecting piece 100 are provided with threaded holes 120, and these threaded holes 120 not only penetrate the protruding blocks 143, but also extend to the clamping portions 142. When the threaded holes 120 are penetrated by the threaded studs 320 and locked, not only can the cross beams 200 be stably fixed on the connecting piece 100, but also additional clamping force can be provided to improve the overall stability of the spliced structure, so that it remains firm under long-term stress or vibration conditions, thereby reducing the risk of loosening of the threaded studs 320 and improving the durability and reliability of the spliced structure.

[0053] Please refer to Figure 5 and Figure 6 In an embodiment, the connecting piece 100 includes two fixing grooves 110, and the extension directions of the two fixing grooves 110 are perpendicular or parallel to each other.

[0054] Specifically, some connecting pieces 100 include two fixing grooves 110, and the extension directions of the two fixing grooves 110 can be perpendicular or parallel to each other. When the fixing grooves 110 are parallel to each other, they can be used for linear splicing of multiple cross beams 200, so that the cross beams 200 extend in the same direction, which is suitable for assembly of frame structures or multi-span structures. When the fixing grooves 110 are perpendicular to each other, L-shaped splicing can be achieved, for example, the spliced steel structure 10 is used at the edge position in the suspended ceiling structure, so that the cross beams 200 can be expanded in different directions, thereby adapting to more complex steel structure layouts.

[0055] Please refer to Figure 7 In an embodiment, the connecting piece 100 includes three fixing grooves 110, and the extension directions of two of the fixing grooves 110 are parallel to each other and perpendicular to the other fixing groove 110.

[0056] Specifically, some connecting pieces 100 include three fixing grooves 110, and the extension directions of two of the fixing grooves 110 are parallel to each other and used for connecting multiple cross beams 200 in the same direction, while the extension direction of the other fixing groove 110 is perpendicular to the two fixing grooves 110 and used for expanding the cross beams 200 in different directions, so that the spliced structure forms a T-shaped three-way branch layout. For example, the spliced steel structure 10 is used at the edge position in the suspended ceiling structure, and this design can realize splicing of multiple cross beams 200 in different directions without adding additional connecting pieces 100, thereby improving the adaptability of the steel structure system.

[0057] Please refer to Figure 8 In an embodiment, the connecting piece 100 includes four fixing grooves 110, and the extension directions of two of the fixing grooves 110 are parallel to each other and perpendicular to the other two fixing grooves 110.

[0058] Specifically, the connecting piece 100 includes four fixing grooves 110, two of which are parallel to each other in the extension direction and can be used to splice multiple beams 200 along the same line, and the other two are perpendicular to each other in the extension direction and can be used to expand the beams 200 in different directions. This design allows the spliced steel structure 10 to form a cross-shaped splicing structure, enabling the steel beams to expand in four directions, for example, when used in the middle position of a suspended ceiling structure, improving the adaptability and space utilization of the structure. This design is particularly suitable for multi-directional force scenarios such as net rack structures, truss structures, and frame support systems, effectively improving overall stability and anti-deformation ability.
